How to Restore database using Cold Backup in Noarchivelog Mode Without Online Redo Logs

Restoring a Cold Backup in Noarchivelog Mode Without Online Redo Logs
====================================================================

1. Shut down the instance.
2. Copy the control files and data files back from the backup.
3. Start up the database in mount mode.
4. Open the database with the OPEN RESETLOGS clause.



Step 1. Shut Down the Instance
--------------------------------------------------------------------------------------


$ sqlplus / as sysdba
SQL> shutdown abort;


Step 2. Copy the Files Back(datafiles and controlfiles) from the Backup without redo logfiles backup
----------------------------------------------------------------------------------------------------

$ cp <backup directory>/*.* < database file directory>


Step 3. Start Up the Database in Mount Mode
----------------------------------------------------------------------------------------------------

$ sqlplus / as sysdba
SQL> startup mount



Step 4. Open the Database with the OPEN RESETLOGS Clause
--------------------------------------------------------------------------------------------------

SQL> alter database open resetlogs;

you will get error


ORA-01139: RESETLOGS option only valid after an incomplete database recovery


{SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery}


SQL>


SQL> recover database;
ORA-00283: recovery session canceled due to errors
ORA-00264: no recovery required


SQL> alter database open resetlogs;
alter database open resetlogs
*
ERROR at line 1:
ORA-01139: RESETLOGS option only valid after an incomplete database recovery


SQL> recover database until cancel;
Media recovery complete.
SQL>

SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-01589: must use RESETLOGS or NORESETLOGS option for database open


SQL>


Now, attempt to open your database with the OPEN RESETLOGS clause:
SQL> alter database open resetlogs;

How to Restore database using Cold Backup in Noarchivelog Mode with Online Redo Logs

Restoring a Cold Backup in Noarchivelog Mode with Online Redo Logs

=======================================================================


1. Shut down the instance.
2. Copy the data files, online redo logs, temporary files, and control files back from the
   backup to the live database data file locations.
3. Start up your database


Step 1. Shut Down the Instance
-------------------------------------------------------------------------------------------

[oracle@mylab bsnl]$ sqlplus "/as sysdba"
SQL> shutdown abort;


Step 2. Copy the Files Back from the Backup
---------------------------------------------------------------------------------------------

[oracle@mylab bsnl]$  cp /u02/backup/bsnl_30082016/*  /u01/app/oracle/oradata/bsnl/

** must be copy files as previous location when take backup so keep location information

Step 3. Start Up the Database
----------------------------------------------------------------------------------

Connect to your database as SYS (or a user that has SYSDBA privileges), and start up your database:
[oracle@mylab bsnl]$ sqlplus "/as sysdba"

SQL> startup;



**It’s as if you set your database back to the point in time when you made the backup.

How to take cold backup of database in noarchivelog mode

Cold Backup of a database in noarchivelog mode
=======================================================

1. Determine where to copy the backup files and how much space is required.
2. Identify the locations and names of the database files to copy.
3. Shut down the database with the IMMEDIATE, TRANSACTIONAL, or NORMAL clause.
4. Copy the files (identified in step 2) to the backup location (determined in step 1).
5. Restart your database

Login as sys user
-----------------------------

SQL> select name,open_mode,log_mode from v$database;

NAME      OPEN_MODE            LOG_MODE
--------- -------------------- ------------
BSNL      READ WRITE           NOARCHIVELOG

SQL>

Step 1. Determine Where to Copy the Backup Files and How Much Space is Required
---------------------------------------------------------------------------------------------------------------


select sum(sum_bytes)/1024/1024 m_bytes
from(
select sum(bytes) sum_bytes from v$datafile
union
select sum(bytes) sum_bytes from v$tempfile
union
select (sum(bytes) * members) sum_bytes from v$log
group by members);



Step 2. Identify the Locations and Names of the Database Files to Copy
--------------------------------------------------------------------------------------------------------

select name from v$datafile
union
select name from v$controlfile
union
select name from v$tempfile
union
select member from v$logfile;

Step 3.Take backup of controlfile and pfile from spfile if database run using spfile or copy pfile  to backup location
-----------------------------------------------------------------------------------------------------------------

SQL> create pfile='/u01/app/oracle/u02/backup/init_bkp_30082016.ora' from spfile;

File created.

SQL> alter database backup controlfile to trace as '/u01/app/oracle/u02/backup/control_bkp_30082016';

Database altered.




** The online redo logs are required to open the database in a normal manner.
If you back up all files (including the online redo logs), then to get your database back to the state it was in at the
time of the backup, you restore all files (including the online redo logs) and start up your database

Step 4. Shut Down the Database
-----------------------------------------------------------------------------------------


[oracle@mylab bsnl]$ sqlplus "/as sysdba"

SQL> shutdown immediate


Step 5. Create Backup Copies of the Files
----------------------------------------------------------------------------------

using OS copy command (cp) to copy database files

cp /u01/app/oracle/oradata/bsnl/* /u02/backup/bsnl_30082016/



Step 6. Start Your Database
----------------------------------------------------------------------------------------
[oracle@mylab bsnl]$ sqlplus "/as sysdba"

SQL> startup
SQL>

backup sql script:
---------------------------

create pfile='/u01/app/oracle/u02/backup/init_bkp_30082016.ora' from spfile;

alter database backup controlfile to trace as '/u01/app/oracle/u02/backup/control_bkp_30082016';

select 'cp ' || name || ' ' || '/u01/app/oracle/u02/backup/' from v$datafile;

select 'cp ' || name || ' ' || '/u01/app/oracle/u02/backup/' from v$tempfile;

select 'cp ' || member || ' ' || '/u01/app/oracle/u02/backup/' from v$logfile;

select 'cp ' || name || ' ' || '/u01/app/oracle/u02/backup/' from v$controlfile;
